Positionen -> Vektor

Positionen -> Vektor#

class miniworlds.positions.vector.Vector(x, y)[Quellcode]#

Represents a 2D vector for use in movement, geometry, and physics.

Supports arithmetic with both other Vectors and 2D tuples.

Beispiele

>>> v = Vector(1, 2)
>>> v2 = Vector(3, 4)
>>> v + v2
Vector(4.0, 6.0)
>>> v + (1, 1)
Vector(2.0, 3.0)
>>> (1, 1) + v
Vector(2.0, 3.0)
